1.4 Data types
In Control FPWIN Pro, variable declarations require a data type. All data types conform to IEC61131-3.
For details, please refer to the Programming Manual or to the online help of Control FPWIN Pro.

1.4.1.1
BOOL
Variables of the data type BOOL are binary variables. They can only have the value 0 or 1, and always have a
width of 1 bit.
The condition 0 corresponds to
FALSE
(e.g. initial value in the POU header) and means that the variable is
switched off. In this case we also speak of the variable not being set.
The condition 1 corresponds to
TRUE
(e.g. initial value in the POU header) and means that the variable is
switched on. In this case we also speak of the variable being set.
The default initial value, e.g. for the variable declaration in the POU header or in the global variable list = 0
(FALSE). In this case the variable is not set during the PLC program start. If this is not the case, the initial value
may also be set to TRUE.
